A light wave has a frequency of `4xx10^(14)Hz` and a wavelength of `5xx10^(-7)` meters in a medium. The refractive index of the medium is

A

`1.5`

B

`1.33`

C

`1.0`

D

`0.66`

Text Solution

Verified by Experts

The correct Answer is:
A
`mu_(g) = (v_(a))/(v_(m)) = (v_(a))/(n lambda_(m))`
`= (3 xx 10^(8))/(4 xx 10^(14) xx 5 xx 10^(-7)) = 1.5`
